Compared to our ESP8266 boards. This upgraded ESP32 board features:

  • Dual cores so the WiFi manager can run simultaneously without yielding
  • Faster processor
  • More GPIO pins
  • More analog input pins
  • More analog output pins
  • Extra UART
What Board should be selected in Arduino IDE to use this ESP32? Which pin is connected to the LED_BUILTIN?
Tools -> Board -> NodeMCU-32S
Here\'s a good tutorial for the initial setup that I followed to get mine up and running:
If I recall correctly from when I used the one I bought the LED pin was pin 2 but if it\'s not 2 then it might be 5 or 9. I\'ve already got mine all wired up in a circuit so I don\'t want to take it out :). Good luck buddy!
